'lheinventionrelates to afruit press and a more particularly to a hydraulic cider-press.

The primary objectof the invention is the.

provision of a press of this character, where- 5 in the juices from fruits, for example, apples,

can be conveniently extracted and the extracting operation is hydraulically controlled, the press in its entirety being of novel construction and is readily portable so that such press may be used in stores or other places for the dispensing of the juices of the fruits on extraction thereof.

Another object of the invention is the provision of a press of this character, wherein a hopper is arranged with crushing rolls, these being driven so that fruits introduced into the hopper will be crushed for their delivery in'a crushed condition into an extractor barrel or cylinder, the latter being movable from receiving position to a position to be operated upon by a hydraulic press mechanism, the latter being of novel form.

A'further object "of the invention is the provisionof a press of this character'fwherein the same may be manually operated or automatically controlled and in the operation the juices, from fruits will be expeditiously extracted therefrom'and the samev delivered for the merchandising of the same, the extracable from receiving to extracting positions and such movement controls the working of the crusher rolls and the hydraulic device of the press.

A still further object of the invention is the provision of a press of this character, which is comparatively simple in construction, thoroughly reliable'and efiicient in its operation, readily and easily operated, strong, durable, and inexpensive to manufacture.

NVith these and other objects in view, the invention consists in the features of construction, combination and arrangementof parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out inthe claims hereunto appended. l i i In the accompanying drawings tori barrel or-cylinder being manually shift- Figure l is a side elevation of the press constructed in accordance Wilt-h the invention.

. Referring to the: drawings in detail, the press comprises a frame A constituting a stand including corner uprights or legs 10 and 11 respectively, longitudinal top and bottom side sills 12 and 13 respectively, these being joined with the legs oruprights 10 and 11 in any desirable manner to effect rigidity. Mounted above the bottom side sills 18 in the stand constituted by the frame A is a juice delivery tray 1% having charge spout 15 at one end.

Built above the frame A and supported hereby is a hopper 16 having a downwardly tapered open discharge bottom 17, while arranged interiorly of the hopper l6 and journaled in the side walls thereof are the axles 18 of crusher rolls 19,.these being arranged opposite each other and in close relation to one another so that fruitsintroduced into the hopper 16 through the open rolls 19 are-rotated reversely through the medium of a train of gears 20, one of which is made; fast to a driven shaft 21 mounted in a bearing 22. This shaft has splined or keyed thereon the shiftable member 23 of a clutch,'its companion member 24: being a dismade a part of a driven gear which is loose upon the shaft 21 and meshes with a driving gear 26 fixed toa stud shaft 27 ]ournaled in a bearing 28, the bearings 22 and 28 being made fast to the frame constituting the stand A. The gear 26 is united with a hand tllI'I1i11g XVl1Gl 29 although in lieu of this wheela belt wheelmay be'employed or a suitable connection had with a power source.

The tray 14 has its sides formed to provide tracks- 30' and upon these tracks is adapted to be slidably mounted an extractor barrel or cylinder 31, the side wall and bot tom being slotted as at 32 and 33 respectively'so as topern'iit the discharge of extracted.

juices therethrough into the tray 14 in the operation of the press. I

Mounted upon the frame A forwardly of the hopper 16 is a hydraulically controlled mechanism which comprises a plunger-cylinder 34, the same being vertically disposed upon brackets 35 1nounted upon the stand and working within this cylinder is the plunger 36 having the presser or piston head 37 which is adapted to be lowered'from normally elevated position into the barrel or cylinder 31 for, action upon its contents for the extraction of the uices therefrom. Next to the cylinder 34 is a fluid tank or cylinder i 38 having arcmovableoover or head 39 so that liquid may be introduced thereinto while at one side of the cylinder-34 is a pump 40, the latter having communication with the lower portion of, the tank or cylinder 38 3 38 will be forcedunder pressure by the pump, 40. through the leadpipe 46 into the cylinder 34 for the operation; of the plunger tof-lower the head 37 thereof into the barrelor cylinder 31 when the latter has been located below such head on the shifting of the barrel or cylinder in the tray 14 as will be obvious. q

The cylinder 34 has at its upper enda return lead47 therefrominto'the'tank or cylinder38 and this lead is'fitted with a'rotatable cut-off, valve 48 having a crank 49 for the turning thereof to'open orclose' thesame. This crank,49 has pivoted thereto an actuator rod 50 which is vertically disposed and slidablymounted, externally upon they-cylinder34 while upon the, plunger 36 is atrip 51 for actuating the actuator rod" 50vvhen thef-plunger has reachedthe limit ofits downwardstroke. The valve 48 which; is

normally closed, that is, when the plunger is at its full uppermost stroke, will be automatically opened to permit the liquid to be returned from the cylinder 34 into the tank or cylinder 38. The trip 51 is in the form of a stem and is made fast in the head 37. The actuator rod 50ihas its lower end outturned and through which plays the stem 51, the latter being fitted with adjustable nuts disposed at opposite sides of the outturned end as is clearly shown in Figure 6 of the drawings.. The plunger carries a crosshead 52 with-which are connected coiled retractile springs 53, these being also connected to a crosshead 54 mounted at the top of the cylinder 34 and these springs 53 function to return the plunger to. normalelevated position and in this upward movement oftlie plunger in the cylinder 34 the liquid forced thereinto by the pump 40 will be driven therefrom through the return lead 47 into the cylinder or tank 38, the lead 46 from the pump 40 being fitted with a suitable liquid check device 55 toprevent the return of the liquid therethrough asdelivered into the cylinder 34 from the tank or cylinder 38 by the pump 40, the return of the liquid to the tank or cylinder 38 being hadthrough the return lead 47 and such return being effected on the elevating of the plunger in said cylinder 34 as will be obvious. I

The extractor barrel or cylinder 31 has exteriorly thereof a double acting cam 56 while suitably mounted at 57 upon the frame A are clutch shift levers 58 and 59 respectively,

these being associated with l the shiftable members 2-3 and 43 of the clutches controlling the operation of the shafts 21 and 42 respectively. The shift levers 58 and 59 are actuated by the double acting cam 56' on the barrel orcylinder 31 so that when the latter is moved beneath the hopper 16 the crusher rolls 19 w-ill be actuated by the driving gear 26 for the crushingof the fruit or fruits introduced into the hopper 16 before delivery into the barrel or cylinder 31. Then when the saidbarrel or. cylinder 31 is shifted beneath the plunger of the hydraulic mechanism the pump40 will be operated from the drive gear 26, the clutches being thrown in or closed by the double acting cam 56 operating the clutch shift levers 58 and 59 as will be apparent. When the. cam 56 rides off of either lever 58 .or 59 the clutch will bethrown out automatically.

Journaled transverselyv in the frame A intermediate thereof is a rocking shaft 60 carrying at opposite sides of the stand the arms 61 which have connection through the medium of the pins 62 working in the slots 63 in the respective ar'ms'61 with theextractor barrel or cylinder 31. One of the arms 61 is extended to provide ahand hold 64 for manual shifting of the barrel or cylinder 31 in'the working of the press. I a

It will be apparent that in the working of the press the fruit to have the juices thereof extracted will be introduced into the hopper 16 and the extractor barrel or cylinder 31 will bepositioned immediately beneath the bottom of such hopper to receive the crushed fruit when operated upon by the crusher rolls 19, these being driven from the driving gear 26. When the desired quantity of crushed material has been delivered to the extractor barrel or cylinder 31 the hand hold 64 is operated to shift the said barrel or cylinder 31 beneath the plunger of the hydraulically controlled mechanism and the pump will be automatically driven, from the gear 26 so that liquid from the tank or cylinder 38 will be forced into the cylinder 34' causing the plunger to be lowered into the barrel or cylinder 31 and thereby extracting the juices from the crushed material, the extracted juices being emitted or discharged through the slots 32 and 33 in the barrel or cylinder 31 into the tray 14 whence the same will be delivered from the spout 15 for the merchandising thereof.

It is of course understood that when the plunger is lowered'the valve 48 is closed in the return lead 47 and immediately upon the throwing out of the clutch by disengaging its member 43 from the member 44 the springs 53 will become active for the automatic elevating of the plunger and simultaneously the valve 43 will be opened so that the liquid within the cylinder 34 will pass therefrom back into the tank or cylinder 38. Each clutch member 23 and 43 isheld open or out of engagement with its companion member 24 or 44 by a spring 65. The pump 40 is mounted upon a bracket 66 carried by the frame A constituting the stand of the press.

From the foregoing it-is thought that the means for each of the mechanisms and so located as to be engageable by the barrel during the movement of the barrel from one position to another. I
